TP3404V Description

Short technical summary and product information.

The TP3404V from Texas Instruments is a Quad Digital Adapter for Subscriber Loops (QDASL) IC, designed for voice and data transmission on twisted pair subscriber loops within PBX systems. This device functions as a companion to the TP3401/2/3 DASL single-channel transceivers.

 

It provides 4 independent transceivers, each operating as an ISDN 'U' Interface for short loop applications. The TP3404V supports 2 B channels and 1 D channel per line, achieving full-duplex transmission at 144 kb/s on a single twisted wire pair using burst mode transmission. The loop range extends up to 6 kft on #24 AWG cable, with a typical range of 1.8 km.

 

Key features include on-chip timing recovery, programmable time-slot assignment, and Alternate Mark Inversion (AMI) line coding for low error rates and reduced EMI radiation. The device operates from a 4.75V to 5.25V supply and is housed in a 28-PLCC package suitable for surface mounting.

 

This transceiver is ideal for PBX line card applications requiring robust ISDN connectivity. Its integrated features simplify system design by reducing the need for external components.
